Parks provide valuable recreational land, habitat, and green space in towns and cities. Because parks are outdoors, they can pose human health risks from air pollution, pests, plants, and the weather.

People who go to a park in a town or city may be exposed to outdoor air pollution and its potential health risks. Pests and insects can sting, bite, or carry disease. If pesticides have been used at parks or on playground equipment, people who use the parks or playgrounds may be exposed to those chemicals. Some wild plants, such as poison ivy, oak, and sumac, can cause skin rashes or allergic reactions if they are touched. Because of the sun’s harmful ultraviolet rays, overexposure to the sun can cause skin cancer, premature aging of the skin, cataracts, and weakened immune systems. If a park includes a stream or creek, the water may be contaminated with pollutants that cause human health problems.

Safety concerns at parks include playground equipment, water recreation and swimming, exposure to extreme heat or cold, and wildlife.
